CREAM-SEPARATOR.

Specification of Letters Patent.

Patented Dec. 11, 1906.

To all whmn t 17u03/ concern:

Beit known that l, Jol-1N R. BosTwIcK, of Clifton Springs, in the county of Ontario and State of New York, have invented a new and useful Improvement in Cream-Separators, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

This invention relates to certain new and useful improvements in vessels for holding milk and cream and commonly known as cream-separators, there being one vessel or 'can within another and connected through an opening in the outer vessel.

The present invention has for its object, among others, to provide convenient, durable, and effective means for joining the two vessels and for locking them together.

Other objects and advantages of the invention willbe brought out and made to appear in the following description and particularly pointed out in the appended claims, reference being had tothe accompanying drawings, which, with the reference-numerals marked thereon, form a part of this specification.

Figure 1 is a plan of the device with a part broken away. Fig. 2 is a front elevation seen as indicated by arrow in Fig. 1. Fig. 3 is a front elevation of` parts at the middle of the device with the locking member removed. Fig. 4 is a front elevation of the inner vessel detached. Fig. 5 is a front elevation of a portion of the outer vessel, better showing the opening in the side thereof. Fig. 6 is a transverse section of the parts at the joining of the vessels. taken on the horizontal dotted line 6 6 in Fig. 2. Fig. 7 is a front elevation of the locking member detached. Fig. S is a side sectionalelevation of the device seen as indicated by arrow S in Fig. 2, the section being on the central vertical dotted line in said Fig. 2.

Referring to the parts shown, l is the main vessel of the device, it being of sheet metal and cylindrical in form, 2, Figs'. 1, 4, and S, being the inner sheet-metal vessel, much smaller and ovoid in plan, as shown. The main vessel 1 is formed with a large vertical opening or slot 3, Fig. 5, surrounded by a thick metallic band or mouthpiece 4, Figs. 1, 3,5, 6, and S, held to place by simple fasteners 5 5.

The inner vessel 2 is provided at the i top with a forwardly-projecting hook 6, Figs. 1 4, and S, in position to rest or catch upon the upper edge of the vessel 1 to aid in supporting the inner vessel in place in the outer vessel. The inner vessel is further formed with a vertical opening 7, Fig. 6, through its narrowest side and opposite the opening 3 in the vessel 1, surrounded by a stout metallic mouthpiece S, Figs. 2, 3, 4, 6, and 8, projecting forward through the opening 3 of the vessel 1 and into the mouthpiece 4 of said openinO 8.

tThe mouthpiece S holds a strip of glass 9 to close the opening 7 therein, secured in place i.

by some simple means, as lines of putty 10, making a close joint, said mouthpiece being formed with a concave seat 11, Fig. 6, for receiving a band 12 of suitable packing material, as soft india-rubber, Figs. 4, 6, and 48. This band or cord ofV india-rubberis preferably circular in cross-section and serves to make a tight joint between the mouthpiece 8 and the adjacent inner face of the vessel 1 around the opening 3 to prevent the escape of water from the said vessel 1.

The mouthpiece 8 of the vessel 2 is formed with forward curvedprojections 13 I18, Figs.

2, 3, 4, 6, and 8, formed upon their opposite outer vertical surfaces with similar ,down- Wardly-extending inclined slots or channels 14 14, in which to receive opposite. inwardlyprojecting short pins or studs 15 15 ofi a de.-

tachable locking member 16, Figs. 1, 2, 6, 7, I

The rear surface of the memberf16 is' vessel 2 is in place inthe main vessel 1, with its mouthpiece 8 reaching forwardthrough i the mouthpiece 4, and the locking memberyl is put to place and 'pressed downward the two vessels will be'iirmly locked or heldftoe IOO gether as if a single piece on account, of the studs 15 l5 iirmly pressing the under .inclined sides of the channels 14 14-=in.the mouthpiece S, and when thus-joinedthe narrow or small side of the vessel 2 is.ad

jacent to the wall of the outer vessel, .with a ..i

crescent-shape space 17, Figs. 1, 6, and 8, between them. Giving the minor vessel 2 the form shown in Fig. 1 and joining its narrow side to the outer vessel provides a large space 23 between the vessels where joined and rendering the space 17 for the water more nearly uniform in horizontal dimensions than if made in other form.

The inner vessel 2 is provided with a horizontal rearwardly-projecting spacer or reach 18,' Figs. 1 and 8, to meet the opposing wall of the main vessel l, as shown, serving to hold said vessel 2 forward in place when in the outer main vessel and also to prevent any lateral vibrations or shaking of the inner vessel-V. The vessel 2 is also provided with a discharge or outlet faucet 19, Figs. 1, 2, 3,

4,- a'nd 81, extending forward through the opening 3 in the vessel 1, the latter being also provided with a discharge-faucet 20.

The locking member or lock 16, Fig. 7, is

formed with semicircular ends and parallel sides, the opening 21 throughit being of sufficient size to permit it to be readily passed over and outside of the rojections 13 13 of the mouthpiece 8 and also ,the outlet-faucet 19, as appears in Figs. 2 and 8. This lock 16 is formed near the top with a forwardly-proj'ecting upwardly-curved finger-rest 22, Figs.

1, 2, 7, and 8, to facilitate in pulling the lock upward when it is wished to unlock the parts for the purpose of removing the inner vessel.

This projection 22 also serves as a rest for the hand when pushing the lock firmly down to its lace in the act of locking the parts.
